Essay on Yellow Fever
The
symptoms of yellow fever start to appear within the timeframe of three to six
days. Majority of the symptoms usually include fever, headache, loss of
appetite and vomiting. There are certain instances where jaundice is being
experienced by people with yellow fever as well as internal bleeding. In terms
of transmission, the yellow fever virus gets transferred to human beings by way
of the bite of the yellow fever mosquito Aedes aegypti (St. Georgiev 266). This
virus is being carried by the female mosquito which gets the blood of the
individual infected by the virus. Once the mosquito bites the skin of the human
victim, the yellow fever virus is then injected into the blood with the aid of
the saliva of the mosquito.
Vaccination
is one of the most effective ways to prevent yellow fever. This is highly
suggested especially for people who would be travelling to places where yellow
fever cases are very rampant. It is usually the case that tourists are the ones
who get sick with yellow fever. The effectiveness of the vaccine will stabilize
after ten days and usually remains effective for a minimum of ten years. There
are certain nations in Asia that are always at risk of experiencing yellow
fever epidemics because of the abundance of mosquitoes that can initiate the
transmission of the yellow fever virus to humans. Thus, to stop this possible
transmission, certain nations require previous vaccination of tourists after
visiting locations that are prone to yellow fever. Vaccination needs to be
validated through the issuance of a vaccination certificate which is considered
effective for ten years. The countries that demand yellow fever vaccination is
released by the WHO. Once the vaccination is impossible to be done for whatever
reason, dispensation could be the next option, and an exemption certificate
provided by vaccination centre supported by the WHO is needed.

Aside
from vaccination, reducing the breeding rate of the yellow fever mosquito Aedes
aegypti is also being done to prevent yellow fever. One method being done is
eliminating the larva, and this is achieved through lessening the presence of water
build-up in the environment. Larvicides are also being used because these
organisms like to feed on the larva of yellow fever mosquitoes. The adult yellow
fever mosquitoes are also being killed through the use of insecticides.
It is
important to remember that yellow fever is being caused by the virus that keeps
on multiplying once it is injected into the blood of the human victim. Thus,
there are many important organs or organ systems that get damaged as the yellow
fever gets serious and left untreated. The liver is one of the organs that get
seriously damaged by yellow fever, and once the liver fails to function
effectively, the skin and eyes develop a yellowish colour referred to as
jaundice (Cefrey 43). Once jaundice starts to happen, the blood loses its
capability to clot which leads to more damage. The uncontrollable internal
bleeding could happen from any part of the body. Damage to the heart, brain, and other
important organs of the body could result to coma and vulnerability to more infections.
Unfortunately,
there is no cure for yellow fever as of this time. Thus, the patients will have
to get hospitalized and undergo comprehensive care due to the possibility of
quick deterioration of the body in certain situations. A symptomatic treatment
involves rehydration and pain relief using paracetamol. To educate someone
about this disease, I would make sure to provide him or her with the relevant
materials and references which could educate him or her about how serious
yellow fever is and what he or she needs to do to prevent getting this disease
or what he or she needs to do upon getting yellow fever.
